Bug#891402: Bug in Apt which bypasses the requirement for user to insert OS Disk when installing

[Michael Grznar <mgrznar1@gmail.com>]

Package: apt
Version: 1.4.8 (amd64)

When installing anything that requires inserting the OS Disk into the CD Drive,
instead of inserting the disk, simply typing "fuck you" (without the
quote marks)
and then pressing enter will make it will continue without the disk in
the drive.
It only seems to behave this way when that particular phrase is used.
Here is a transcript:

# apt install g++
Media change: please insert the disc labeled
 'Debian GNU/Linux 9.3.0 _Stretch_ - Official amd64 DVD Binary-1 20171209-12:11'
in the drive '/media/cdrom/' and press [Enter]
# fuck you
Setting up g++


I suggest removing the part of the source code that enabled that behavior.

I am using Debian GNU/Linux 9.3.0, kernel 4.9.0-6-amd64
